I can't see a problem in Static_02 file,
I have also tested both steps (step1 & step2).
step1:
Static_02 = only working
Static_02 + 1 other static = working
Static_02 + 2 other static = working
You should use for the first step, the static file with the lowest MAE.
After first step add, the other 2 for step 2.
You should not only append the parameter, you have to save the parameter also!!!
